Help with Pectoralis Major Muscle Pain and Symptoms
Warm Therapy Gel for Chest, Shoulder and Upper Back Muscle Pain Caused By The Pectoral Muscles
Sombra Warm Therapy Pain Relieving Gel is a pain relieving gel that I use both personally and professionally in my massage therapy practice. Unlike other over the counter heating creams, it provides warmth without burning heat. Applying Sombra to the chest muscles and into the shoulders can help relieve soreness and stiffness in the chest and front shoulder area. It can also help relieve upper back pain which is often a result of tight pectorial muscles. I recommend Sombra for chronic pain and chronically sore tight muscles.
Cold Therapy Gel For Pectoralis Muscle Injury and Pain
Biofreeze Pain Relieving Gel is an excellent pain relieving gel and I use it for those who have sudden onset muscle pain or recent injuries. It is better than warm therapy gels and creams for recent injury muscle pain as it cools the area much like ice and does not promote swelling. A recent study showed that Biofreeze decreased pain 2 times more than ice and the pain relief lasts 9 – 10 longer. If your pain is from a recently pulled pec muscle I would recommend Biofreeze.
Hot Cold Packs For Pectoralis Pain and Injury
SofTouch Large Hot Cold Pack is a large pack that can be used for hot or cold treatment. The pack is large enough to lay across the chest to treat the pectoralis muscle and cover the upper back to relieve upper back pain caused by the pec muscles. The inside of the pack contains a clay like substance that remains soft and pliable so you can mold the pack to your body. The outside of the pack is wrapped with soft suede like material that does not shock the skin when touched. My clients love this pack and it is now the only hot and cold pack that I use in my massage therapy practice.
Relax and Stretch The Pectoral Muscles To Help Shoulder, Neck and Upper Back Pain
Soothe-a-ciser: Relief for neck and shoulder pain helps relieve pressure and pain in the neck and shoulders. 10 – 15 minutes laying on the pillow allows muscles in the neck, chest, shoulders and upper back to relax and can relieve or even stop some headaches. It can work especially well for those with tight painful pectoral (chest) muscles, and people who have slumping upper posture or rounded shoulders. A great pillow for people who work at desks and computers!
Braces and Support for Pectoral Muscle Shoulder and Upper Back Pain
Rounded shoulders and slumping upper body posture are often caused by shortened tight pectoralis muscles which over stretches upper back muscles causing sore and painful upper back muscles. If you are having upper back pain across the shoulders, going down the middle upper back to the shoulder blades, chances are the pain is caused by the pectoralis muscles.
ShouldersBack Posture Support gently pulls your shoulders back helping you maintain straight correct posture while stretching and elongating the chest muscles.
I use this brace myself when I begin to feel twinges of pain in my shoulders and upper back. I have recommended it to family, friends and clients who have pain due to slumping upper body and rounded shoulder posture. If you have rounded shoulders, begin using the brace slowly for short periods of time. As your body adjusts, you can tighten the support and use it for longer time periods. This brace is not a rigid support, you can still move comfortably and freely, it does not forcibly hold your shoulders down and back.
